CAPPED EYELET FOR ATTACHING SNAP FASTENERS Filed` May 20, 1965 United States Patent O 3,333,306 CAPPED EYELET FOR ATIACHING SNAP FASTENERS Domenic J. Daddona, Jr., Waterbury, Conn., assignor to Scovill Manufacturing Company, Waterbury, Conn, a corporation of Connecticut Filed May 20, 1965, Ser. No. 457,309 2 Claims. (Cl. 24-216) ABSTRACT OF THE DISCLOSURE This invention relates to what are generally known in the trade as capped eyelets, such as used for attaching snap fastener parts, buttons and the like to a garment or other articles to be fastened.

Such a. capped eyelet consists of a hollow shank with a Wide head flange to which is attached a covering cap usually of dome shape.

During the eyelet setting operation when the eyelet is riveted into the fastener part, there is required a substantial endwise pressure upon the eyelet which results in a marring marking of the cap itself. This is due to the heavy pressure concentrated at the base of the shank against the domed cap. This has proven so objectionable that in many instances a reenforcing plate is interposed between the eyelet and the cap. This, of course, is more expensive and more bulky.

A partial solution to the problem is proposed in Patent 2,759,237 dated Aug. 21, 1956, whose assignee is also the owner of the instant application. The two-piece capped eyelet disclosed in that patent works sufficiently well when the head is not too large in comparison to the size of the eyelet shank or barrel. However, its usefulness is limited to certain relative dimensions of the eyelet shank and head diameter.

T-he principal object of my invention, therefore, is to provide a two-piece capped eyelet of novel construction which will be useful regardless of the relative dimensions of the two parts. At the same time, the economy of only two easily manufactured sheet metal parts is maintained.

In the accompanying drawing, I have shown for purpose of illustration, one embodiment which the invention may assume in practice. In the drawing:

FIG. 1 is a central sectional view through a fastener attached to a portion of a garment or the like, `by means of my improved capped eyelet;

FIG. 2 is a central section showing the complete capped eyelet before the setting operation, with the eyelet section taken along line 2-2 of FIG. 3;

FIG. 3 is a plan View of the eyelet by itself; and

FIG. 4 is a vertical section on line 4 4 of FIG. 3.

In FIG. 1, there is shown a typical fastener member 5 which may be attached to a portion of a garment or the like, 6. The fastener member 5 has a hole 7 to receive 3,333,306 Patented Aug. 1, 1967 rice 2 the end of the eyelet shank 8, the end portion of which is riveted over by a bead rolling operation against the fastener member around the hole as indicated at 9.

The eyelet has a head flange 10 which can be slightly dome-shaped as indicated in the drawing, or it may be flat. The flange 1l) joins the hollow shank 8 in a relatively large radius 11. Reenforcing means are provided which is equivalent in function to a ller disc formerly used in many caps but without requiring the expense of making and assembling such a third piece. The re-enforcing means here shown take the form of a pair of scallops or wings 12 and 13 which are cut away from the head flange 10, leaving the holes 14 and 15. These wings are folded over to project radially inwardly into close proximity to each other so as to extend over the line of the shank Wall, and preferably the wings are of such an extent that they overlie substantially the entire adjacent end of the shank 8. The cut-outs 16 on the inner edges of these wings are for the purpose of providing a lhole to permit the flow of the solution which may be -used in a plating operation.

The other of the two pieces of the assembly is the domed cap 17 which is attached to the periphery of the eyelet flange 10 by a curled-over edge 18.

In the initial position before assembling with the fastener 5, the inner surface of the cap 17 is closely adjacent or directly against the reenforcing wings 12 and 13. If desired, such wings may be also outwardly domed to conform to the shape of the cap initially. During assembly, the necessary endwise pressure applied to the shank 8 to form the bead 9 may apply some pressure at the outer edges of the wings 12 and y13, but the radius 11 will quickly fold against the wings so that the real hard pressure comes at the final stage where the shank wall comes against the inner surfaces of the Wings. It is these localized areas in line with the wall of the shank 8, that the pressure is concentrated and where marring of the cap will be more likely to occur.

What I claim is:

1. A two-piece capped eyelet vfor attaching fastener members wherein one piece is a sheet metal rivet eyelet lhaving a hollow shank, a circular head flange integrally joined to the shank wall at one end of said shank, and reenforcing means comprising wings punched from the sheet metal of said flange and folded over to project radially inwardly so as to extend 4across .and cover the major portion of said end of the shank; and wherein the second piece is a cap of dome shape having its outer edge secured to the periphery of said head flange, the inner surface of said cap being closely adjacent said wings so that said wings will prevent marring of said cap by endwise riveting pressure applied to said eyelet shank.

2. A two-piece capped eyelet as defined in claim 1 wherein said reenforcing means comprises a pair of oppositely disposed punched out wings covering substantially the entire end of said shank which is joined to said head flange.
